What Does Corticobasal Degeneration Mean
Corticobasal refers to the two parts of your brain the disease affects. Degeneration refers to deterioration or loss of function.
The disease affects your:
- Cerebral cortex: This outer layer of nerve tissue aids your memory, learning, voluntary movements and senses.
- Basal ganglia: This group of nerve cells is critical for learning and motor functions.
Parkinsons Disease Treatment: What Are My Options
There are various treatment options for Parkinsons disease. After you receive a formal Parkinsons diagnosis, your doctor will explore these possibilities with you. Common Parkinsons disease treatment options include:
- Home remedies for Parkinsons
- Lifestyle changes
Your doctor may recommend one medication or a combination of Parkinsons disease treatments. Your course of treatment will depend on various factors, such as:
- Any other medical conditions in you or your family
- Other prescribed medications
- Your age and overall health status
Before you and your doctor can decide which treatment is right for you, you will need to explore treatment options for Parkinsons disease in more detail.

Stages Of Parkinsons Disease
Experts have identified a general Parkinsons progression and created a set of Parkinsons stages, which can help determine where you are at in the disease and what your prognosis might be. However, not everybody progresses through Parkinsons disease in the same way or on the same time frame. Some people skip stages or rapidly progress to later stages. Others live for many years with mild or moderate Parkinsons and never reach the more advanced stage of the illness.
Here are five commonly recognized stages of Parkinsons, including what symptoms you might expect. Treatment also can occur during these stages to help prevent or delay later stages of the illness. This can include medication, physical therapy, and lifestyle changes, such as a healthy diet and exercise program.
What Makes Pd Hard To Predict
Parkinsonâs comes with two main buckets of possible symptoms. One affects your ability to move and leads to motor issues like tremors and rigid muscles. The other bucket has non-motor symptoms, like pain, loss of smell, and dementia.
You may not get all the symptoms. And you canât predict how bad theyâll be, or how fast theyâll get worse. One person may have slight tremors but severe dementia. Another might have major tremors but no issues with thinking or memory. And someone else may have severe symptoms all around.
On top of that, the drugs that treat Parkinsonâs work better for some people than others. All that adds up to a disease thatâs very hard to predict.
Improving Mobility Strength And Balance
Staying mobile and self-sufficient is top of mind for people living with Parkinson disease. Stiffness is also a known problem with the disease. This rigidity can cause poor posture and pain that leads to other functional problems. A physical therapist can help with these problems. PTs guide people with Parkinson through moves and stretches to increase mobility, strength, and balance.

Bryans Early Onset Parkinsons Diagnosis
Bryan is a 35-year-old nurse, rock climber, husband, and new father to a four-month-old baby boy. He is also someone who is living with YOPD. YOPD is defined as Parkinsons that is diagnosed before the age of 50 and includes about 10% of people living with PD. Younger people will experience the disease differently than those who are diagnosed older, in part due to their different life circumstances. Employment, new relationships, and parenthood add particular challenges that those who are diagnosed older may not have to navigate. When and how to disclose the diagnosis is also of particular concern.
Motor Neuron And Dopamine Controls
The motor disability symptoms of Parkinsons disease result from the loss of dopamine secreting pigmented cells, in the pars compacta region of the substantia nigra . The substantia nigra is a very small area located deep within the brain and in PD patients these dopaminergic neural cells of substantia nigra degenerates and dies, only few live neurons in this region are observed in PD brain tissues than in the normal brain tissue. The loss of dopaminergic neurons leads to the loss of dopamine and dopamine is the major neurotransmitter which relays neuronal signals from the brain to other motor centers. The lack of dopamine in PD patients disturbs the movement control of the patients and mood, behavior, thinking and sensation of the patients .

How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.
How Is Parkinsons Diagnosed
Doctors use your medical history and physical examination to diagnose Parkinson’s disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.
Researchers believe that in most people, Parkinson’s is caused by a combination of environmental and genetic factors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.
Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

Don’t Miss: Are Essential Tremors Related To Parkinson’s
What Can I Expect If I Have Essential Tremor
Essential tremor is usually progressive, meaning it gets worse over time. This is usually a slow process. The average rate that arm or hand tremors get worse is between 1.5% and 5% a year.
Essential tremor starts small and usually only affects your hands at first. Over time, usually many years, the tremors may spread to affect your arm and head. As the condition progresses, you may begin to struggle with certain activities and may need help to do them.
How long does essential tremor last, and can it go away?
Essential tremor is a permanent, life-long condition once it starts. Its not curable, and it doesnt go away on its own.
Whats the outlook for essential tremor?
In years past, the term benign, meaning harmless, was a standard part of its name, as in benign essential tremor. However, experts now recognize that while essential tremor isnt harmful directly, it can cause severe disruptions in your life.
People with more severe tremors struggle with activities such as cooking, using kitchen utensils, drinking from a cup, hygiene activities, grooming and dressing. Some people who have essential tremor eventually cant live independently and need to live with family or in an assisted living or skilled nursing facility setting.
How Is Parkinson’s Disease Managed
Your doctors will tailor your treatment based on your individual circumstances. You will manage your condition best if you have the support of a team, which may include a general practitioner, neurologist, physiotherapist, occupational therapist, psychologist, specialist nurse and dietitian.
While there is no cure for Parkinson’s disease, symptoms can be treated with a combination of the following.

Will Parkinsons Disease Treatment Affect My Prognosis
While no treatment will affect your Parkinsons disease prognosis, many patients find that a combination of medication, physical therapy and positive lifestyle changes help them control the symptoms of Parkinsons even in the late stages of the disease.
If you have any questions about your diagnosis or youre concerned about your treatment options, talk to your doctor. You can also seek advice and support from the National Parkinsons Foundation Helpline by calling 1-800-4PD-INFO .
Parkinsons Disease Life Expectancy
Most people with Parkinsons can have a normalor close to normallife expectancy today, thanks to new medications, therapies, and other treatments. Survival rates for those with typical Parkinsons disease are either the same as for the general population or shortened by about a year, studies show.
Risk factors for earlier mortality with Parkinsons include:
Being diagnosed before age 70
Having cognitive impairment early in the disease
Developing Parkinsons dementia
People with Parkinsons dont die from the disease itself, but from associated complications, such as infections or injuries . Cardiovascular disease is another common cause of death.
Treatments and lifestyle improvements, can help forestall cognitive decline, lower your risk of falls and strengthen your cardiovascular system. These can help improve your quality of life and, by slowing progression of the illness, potentially keep you living longer.
Researchers are continuing to explore new treatments that they hope will one day lead to better therapies for Parkinsons, which will result in an improved prognosis.

How Is Corticobasal Degeneration Treated
For corticobasal degeneration, therapies focus on helping compensate for the difficulties with coordination and speech. Medication therapies may help manage muscle jerks or help improve attention or mood-related changes. Treatments for other movement disorders like Parkinsons disease arent often effective. There isnt a treatment to cure the disease.
Your healthcare provider may recommend:
- Occupational therapy to help you learn new ways to complete daily tasks and maintain independence.
- Physical therapy to help maintain mobility and ease muscle contractions.
- Speech therapy to aid communication and swallowing.
How Do I Take Care Of Myself
If you have Parkinsons disease, the best thing you can do is follow the guidance of your healthcare provider on how to take care of yourself.
- Take your medication as prescribed. Taking your medications can make a huge difference in the symptoms of Parkinson’s disease. You should take your medications as prescribed and talk to your provider if you notice side effects or start to feel like your medications aren’t as effective.
- See your provider as recommended. Your healthcare provider will set up a schedule for you to see them. These visits are especially important to help with managing your conditions and finding the right medications and dosages.
- Dont ignore or avoid symptoms. Parkinsons disease can cause a wide range of symptoms, many of which are treatable by treating the condition or the symptoms themselves. Treatment can make a major difference in keeping symptoms from having worse effects.

- Memory issues or signs of dementia.
- Problems with speech, swallowing or breathing.
What should I ask my provider?
You may want to ask your healthcare provider:
- Could a different disease cause these symptoms?
- What should I plan for as the disease progresses?
- Which medications or other therapies help?
A note from Cleveland Clinic
Corticobasal degeneration is a rare, slow-progressing brain disease that affects memory, communication and movement. It causes symptoms similar to Parkinsons disease: muscle spasms and twitches, tremors and slowed movements. It can also affect your ability to talk, swallow and complete simple tasks like buttoning a shirt. As the disease progresses, dementia or memory loss may occur. There currently isnt a cure for the disease. But therapies for speech and movements may help you maintain independence longer.

What Causes The Condition
Although there are several recognized risk factors for Parkinsons disease, such as exposure to pesticides, for now, the only confirmed causes of Parkinsons disease are genetic. When Parkinsons disease isnt genetic, experts classify it as idiopathic . That means they dont know exactly why it happens.
Many conditions look like Parkinson’s disease but are instead parkinsonism from a specific cause like some psychiatric medications.
Familial Parkinsons disease
Parkinsons disease can have a familial cause, which means you can inherit it from one or both of your parents. However, this only makes up about 10% of all cases.
Experts have linked at least seven different genes to Parkinson’s disease. They’ve linked three of those to early-onset of the condition . Some genetic mutations also cause unique, distinguishing features.
Idiopathic Parkinsons disease
Experts believe idiopathic Parkinsons disease happens because of problems with how your body uses a protein called -synuclein . Proteins are chemical molecules that have a very specific shape. When some proteins dont have the correct shape a problem known as protein misfolding your body cant use them and can’t break them down.
With nowhere to go, the proteins build up in various places or in certain cells . The buildup of these Lewy bodies causes toxic effects and cell damage.
The possible causes are:

Whats Different About Young
The age of diagnosis matters for a variety of reasons, from probable causes of early cases to symptoms and treatment:
- Genetics. As with any case of Parkinsons disease, the exact cause is usually unknown. That said, The young-onset cases of Parkinsons disease are, on average, a bit more likely to be familial or genetic, says Gregory Pontone, M.D., director of the Johns Hopkins Movement Disorders Psychiatry Clinic.
- Symptoms. In many patients with YOPD, dystonia is an early symptom. People with YOPD also report more dyskinesia . They also tend to exhibit cognitive problems, such as dementia and memory issues, less frequently.
- Progression. Patients with young-onset Parkinsons appear to have a slower progression of the disease over time, says Pontone. They tend to have a milder course, staying functional and cognitively intact for much longer.
- Treatment. Most patients with Parkinsons take the medication levodopa. However, other drugs, such as MAO-B inhibitors, anticholinergics, amantadine, and dopamine receptor agonists, may be used before levodopa.
Changes In Cognition And Parkinsons Disease
Some people with Parkinsons may experience changes in their cognitive function, including problems with memory, attention, and the ability to plan and accomplish tasks. Stress, depression, and some medications may also contribute to these changes in cognition.
Over time, as the disease progresses, some people may develop dementia and be diagnosed with Parkinsons dementia, a type of Lewy body dementia. People with Parkinsons dementia may have severe memory and thinking problems that affect daily living.
Talk with your doctor if you or a loved one is diagnosed with Parkinsons disease and is experiencing problems with thinking or memory.
Don’t Miss: What Does Parkinson’s Do To The Brain
How Is Parkinsons Disease Dementia Diagnosed
No single test can diagnose Parkinsons disease dementia. Instead, doctors rely on a series or combination of tests and indicators.
Your neurologist will likely diagnose you with Parkinsons and then track your progression. They may monitor you for signs of dementia. As you get older, your risk for Parkinsons dementia increases.
Your doctor is more likely to conduct regular testing to monitor your cognitive functions, memory recall, and mental health.
What Are Parkinsons Delusions
Delusions are thoughts that arent grounded in reality. Theyre not as common as hallucinations, affecting only about 8 percent of people with Parkinsons disease. But they are harder to treat.
The most common delusions involve paranoia for example, the feeling that people are out to get you, or that your partner is cheating on you. Having these thoughts can lead to aggressive or even dangerous behavior.
Youll start with a visit to your doctor for an evaluation. Your doctor may diagnose you with this condition if you:
- have had symptoms like hallucinations and delusions for at least 1 month
- dont have another condition that could be causing these symptoms, like dementia, delirium, major depression, or schizophrenia
Not everyone with Parkinsons disease will develop psychosis. Youre more likely to have this if you:
There are two possible causes of Parkinsons psychosis:
- changes in levels of brain chemicals like serotonin and dopamine from the disease itself
- changes in levels of these chemicals from medications that treat Parkinsons disease
Dopamine is a chemical that helps your body move smoothly. People with Parkinsons disease have lower than normal levels of dopamine, which causes their body to move stiffly.
Drugs that treat Parkinsons improve movement by increasing dopamine levels. Yet they can sometimes cause psychosis as a side effect.
